I am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?
I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

View 14 RepliesI'm relearning VB.net just for fun, so consider me new at this. I'm trying to write a program where the user can input a list of names or numbers, and the program will randomly pick one of those names or numbers. So far, I can get it to randomly generate numbers based on what I put in the code, but I don't know what I should use for the user to input the data, and how to code it so that the program will pick from that data.

I have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.

I am currently working on a project on Microsoft Visual Basic 2008 Express Edition, in which I need to move an image across the form from one end to the other without moving it in a straight line. I want to try and randomize the image while it moves in a general direction, but I am not sure how. I also am trying to get four images to do this, from top to bottom, bottom up, left to right, and right to left.

Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option)
All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.

I can run this 100 times under the exact same conditions and it seems like 40 times it will crash with the following error:
"Cannot access a disposed object. Object name: 'frmImportExport'."
It will either die on

Me.Invoke(__Delegate)
or

The form isn't being disposed manually anywhere that I see, and this code is being executed on formload. It's a subform that is to be displayed within a main form.

how to do this certain section of it. I want it to take a group of first names and randomly pair one with a last name randomly selected from a separate group. something like this:
Group 1-BobJoeBrianJillJorge
Group 2-SandersRientzLopezGumpStaudmann then output something like "Brian Staudmann" or "Jorge Gump"
Except I want a significantly larger selection of first and last names in each group. Would it be best to save them in an array? A String? Parse from textfiles?

Right now I have a program that checks login credentials against my Access(2003) database.It works, but the problem I'm having is that it's checking if the file.exist to frequently and with no real pattern. How I'm doing it isI have a My.Setting that saves the file path string as well as the connection string, during form_load I check if the My.Setting path string exist, if not then use an openfiledialog to find the file. Right now I have the database in a public drive, which is why I think that my program thinks that the file doesn't exist sometimes. This is how I'm doing all of the above:
'Some global variables commented out
'Dim log As String = My.Settings.loginStr
'Dim logCon As String = My.Settings.loginCon
